The thick portions are composed of at least two kinds having different lengths in a radiation direction and formed to be gradually thinner in the radiation direction from the inner circumferential side to the outer circumferential side. With this configuration, separate vibrations in the diaphragm can be suppressed. Further, a speaker device provided with the diaphragm having the above-described configuration can reproduce sounds faithfully in accordance with input signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Diaphragm and speaker device provided with the same","description":"A diaphragm is provided with a plurality of thick portions radially from an inner circumferential side to an outer circumferential side.
